Battery terminal connector

Abstract

A battery terminal connector provided between a battery cable and a battery post erected from the battery body, which is made of a single metal plate, is provided with two holes through which the battery post is secured when the metal plates is folded to form a metal body, and has a stud bolt for connecting the battery cable. The erected stud bolt is firmly held by two wing portions formed in the lower plate of the metal body, which wing portions are bent at a right angle to embrace the square head of the stud bolt. A flat portion between the wing portions supports the bottom face of the inverted stud bolt.

What is claimed is: 
     
       1. A battery terminal connector formed of a metal sheet material, which is punched and pressed from a single metal piece comprising: a metal body, which is formed by folding the metal sheet material, having a post fixing portion, a stud bold fixing portion and a cylindrical portion;   a fixing hole having a variable diameter for receiving a terminal post therein provided in the post fixing portion;   a stud bolt, which has a square head, provided in the stud bolt fixing portion;   a fastening bolt passing through the cylindrical portion for compressing of the diameter of the fixing hole;   said stud bolt fixing portion comprising an upper plate portion having a stud bolt hole formed therein and a lower plate portion of the metal sheet material further comprising;   a pair of wing portions adapted to be bent at a right angle to the plane of the sheet metal material provided in the lower plate portion to sandwich the square head of the stud bolt from the opposite sides thereof and support the square head upwardly; and   a pair of wing portions provided in the upper plate portion to embrace said wing portions provided in the lower plate portion which sandwiches the square head of the stud bolt, and the threaded portion of the stud bolt being projected through said stud bolt hole in the upper plate portion;   wherein said lower plate portion provided with a pair of wing portions is made of a single metal piece, whereby the strength of said wing portions of said lower plate portion is increased.   
     
     
       2. A battery terminal connector as set forth in claim 1, wherein said cylindrical portion has a slit in the circumferential direction thereof for compressing the diameter of the fixing hole by threading of the fastening bolt in said cylindrical portion and said cylindrical portion is provided on the lateral position of the metal body opposite to the position at which said stud bolt is located. 
     
     
       3. A battery terminal connector as set forth in claim 1, wherein said lower plate portion has an end portion and wherein said wing portions in the lower plate portion are located at opposite sides of the end portion of the lower plate portion. 
     
     
       4. A battery terminal connector as set forth in claim 3, wherein each wing portion in the lower plate portion has an area substantially the same as that of the side surface of the square head of the stud bolt.
